Tower crane safety monitoring method and system

Abstract

The invention provides a safety monitoring and method and system of a tower crane. Within the first time frame, the hanging object-work distance between a hanging object and a work face of the tower crane, the relative position of the hanging object to the tower crane and the relative position of a worker on the work face relative to the tower crane are acquired; based on the relative position ofthe hanging object to the tower crane and the relative position of the worker relative to the tower crane, the position change trend of the worker relative to the hanging object within the first timeframe is acquired; and furthermore, according to the position change trend of the worker relative to the hanging object within the first time frame, through combination with the hanging object-work distance, whether the worker is about to enter an early warning dangerous area under the hanging object within a second time frame or not is judged, and a preset early warning signal is output. According to the safety monitoring and method and system of the tower crane, when the worker is about to enter the early warning dangerous area, an alarm is given to the worker and / or a driver of the tower crane, and the accident happening risk is reduced.

Description

technical field [0001] The present disclosure relates to the field of safety monitoring, and more particularly relates to a method and system for tower crane safety monitoring. Background technique [0002] When the tower crane is hoisting, there is a potential safety hazard that the hanging object will fall accidentally. There is a dangerous area directly below the hanging object that changes with the position of the hanging object. When someone enters the dangerous area on the working surface, the risk of injury from falling objects increases immediately. The current tower crane safety monitoring solution is mainly to monitor the safety status of the tower crane itself by installing various sensors on the tower body, that is, to collect limit data such as wind speed, rotation, amplitude, height, weight, etc. to monitor whether the tower crane is in a state of safe operation; As for whether there are people entering the dangerous area directly below the hook, it is mainly ...

AI Technical Summary

Problems solved by technology

[0003] The above scheme needs to be observed by the driver's naked eyes to avoid the risk of falling objects and hurting people. In the case of poor visibility, there may be misjudgments or missed judgments, and it will be affected by the driver's subjective factors (for example, the driver due to fatigue, carelessness, etc.) The reason has not been noticed), there are great disadvantages
